cellular respiration Flashcards
(27 cards)
Where does the majority of cell respiration take place
mitochondria
where does the citric acid cycle occur
mitochondrial matrix
where does oxidative phosphorylation occur
cristae (folds of mitochondrial inner membrane)
where does glycolysis occur
cytoplasm
when is carbon dioxide produced during cell respiration
pyruvate oxidation and citric acid cycle
what types of organisms undergo cellular respiration
eukaryotes
what stage of cell respiration can occur in a anaerobic environment
glycolysis
what is the relationship between breathing and cellular respiration
it supplies the oxygen needed to produce atp, the bodies energy
what is the main purpose of the citric cycle
Oxidizes acetyl-CoA to produce carbon dioxide, NADH, FADH2
what is the main purpose of oxidative phosphorylation
produce atp
what is the main purpose of glycolysis
break apart glucose
what are the main products of the citric acid cycle
ATP, NADH, FADH2, and CO2 as a waste/byproduct
what are the main products of glycolysis
pyruvate, ATP, NADH
what are the four stages of cellular respiration
glycolysis
pyruvate oxidation
citric acid cycle
oxidative phosphorylation
the main products of oxidative phosphorylate are
ATP
the functions of nadph and fadh2 are
to transfer electrons
the final electron acceptor of cell respiration is:
oxygen
what are the main products of pyruvate oxidation
acetyl CoA, NADH, and carbon dioxide
what is the main purpose of pyruvate oxidation
to oxidize pyruvate to create acetyl CoA
the enzyme that produces ATP during oxidation phosphorylation is
ATP synthase
prior to the citric cycle, pyruvate is converted into:
acetyl-COA
how is cellular respiration related to photosynthesis
tthe products of photosynthesis are used as reactants in cellular respiration to produce energy , while the carbon dioxide of cellular respiration is used as a reactant in photosynthesis
during oxidative phosphorylation, h20 is formed. where does the oxygen come from?
molecular oxygen inhaled
complete oxidation of glucose produces how many carbon dioxide molecules
